## Discrepancy

AIRCRAFT ARRIVED AT HOME STATION AND UPON A POST-FLIGHT INSPECTION FOUND THAT THE LEFT HAND REAR DOWNLINK ANTENNA POLE SECTION WAS MISSING--DETACHED FROM THE ANTENNA'S BASE. DEPARTURE OF THE ANTENNA POLE HAPPEN SOMETIME DURING THE AIRCRAFT'S 6.8 HOUR FLIGHT.  MANUFACTURING OF THE ANTENNA POLE IS ATTACHED TO THE BASE WITH SOME KIND OF GLUE AND IS CLEARLY THE WEAK POINT OF THE ASSEMBLY.  RESEARCH INTO THIS AIRCRAFT AND OTHER OPERATOR SAME MODEL TYPES FOUND THAT THIS INCIDENT IS THE SIXTH SIMILAR HAPPENING.
